In board mode, the whole space can be dedicated to the 2D board.
In discussion mode, first divide the screen in half so the left is for discussion and the right is for board. On the left side, the half-section is further halved into a chat section and a summary section. It is important each feels equal in weight, that the summary feels as important as the ongoing discussion. On the right side, put the focus on the top, such that the board feels like a square. The square shape will give the psychological feeling that we see "more at once".
